Our intelligent e sign tool uses the sender’s and signer’s email addresses to authenticate e signatures for any PDF sign document. The only way to access and sign e-sign packages is through your personal email access, which ensures that only the designated signer or signers can view, edit, and add their signature to the files. Our secure technology establishes an encrypted link between our web server and your browser so that all data remains private. We only store each file on our server for 24 hours to limit any unauthorized access.

The e-sign PDF signatures & files are then permanently removed from our PDF online servers. As the sender of a document, your permissions will differ from those of the signer. In the PDF sign process, signers only have the ability to add their signature to the document, senders are given administrative permissions and access to the documents, which allows them to create, edit, review, and track any signature for their documents. All e sign files are made available to users through the Soda PDF inbox.


A digital signature might be used to approve or reject documents internally, but an e-signature is primarily used by a business or an individual as a legal signature solution for when they or every required signee cannot directly be in the same room or location. Whether to approve contracts, sales forms, agreements, or to save time and increase productivity, our software can help provide you and your signees with an electronic signature experience that keeps a safe distance between people and paper.
